BC - I thought all belt dressing did was cause the rubber to swell slightly which can prolong a belt on its way out. Sort of like moisturizing skin. I think it also adds a bit of tackiness, but a slipping belt is due to bad tension or a worn surface and I dont think lubing it up will make a difference long term.
